Help!!!! for first time budget build R5500 is this okay????

Hey guys i am by no means an expert in all of this but have done my fair share of research and have come up with these parts for a new pc...

please let me know if you have any better ideas but keep in mind i don't want to spend anymore money unless absolutely necessary, i also have no idea if all these parts will work together so let me know if somethings wrong i.e psu or GPU is possibly overkill?

The pc is for gaming at 1024x768 (32inch lcd tv) and have no intention of overclocking in the near future,thanks in advance...

i also have a seagate HD 750gb 7200rpm from an old pc...

Total is R5077

I was told to rather go with the HD5670 as at the resolution im playing at(1024x768) the HD6790 will be a waste then i could also save on a cheaper psu say 420w please give me your thoughts on this...

Hi & welcome to myBB.

The Antec HCG400 would work just fine for that HD6790. The HCG520 would run the high end HD6970 quite easily.

Only the Intel Socket 1366 motherboards took RAM in multiples of 3. All the other motherboards takes RAM in multiples of 2.

What games do you intend to play, and where are you going to buy the components?

Okay well then ill go with the 400w Antec thanks...i currently have the COD series, metro 2033,dead island and starcraft 2, so i believe at the low resolution im playing at it should run quite smoothly?...i think im going to buy from the website in my links(rebeltech) cos they seem to be the cheapest if you have cheaper options then pls let me know
